METAL-TRANSFER DEVICE.

Specification of Letters Patent.

Patented April 16, 1907.

Application filed June 19, 1905. Serial No. 265.868.

tion, of a hotbed equipped with my im- E Fig. 2 is a plan, and

proved transfer device. Fig. 3 is a sectional side elevation, of thetransfer device. Fig. 4 is an end elevation, and Fig. 5 a sectionalelevation on the line V V of Fig. 2.

My invention relates to the class of devices for transferring metallaterally on supportingwvays; and the object of the invention is toprovide a simple and'eflicient device by which metal may be movedsidewise on hot I beds or suitable supports; further, to provide a dogor pivot pushing device which may be thrown into inoperative positionand held in such position without manual operation; further, to providea pushing device which may be thrown into and out of operation at thewill of the operator without manual operation of the dog or pushingdevice.

The further object of the invention is to prevent distorting or nickingof the metal by the action of the dog in returning.

In the drawings, 2 indicates the rail of the hotbed, and 3 the roller ofthe table leading from the mill to the hotbed. The hotbed is made up ofa series of these rails, which are separated apart from each other, therollers carrying the beam. or metal forwardly along the side of thehotbed. Below and between certain of the supporting-rails of thehotbedare located supporting-guideways 4, which are shown as consisting ofchannels with their flanges projecting upwardly. In these channels slidethe transfer devices, which are shown in detail in Figs. 2, 3, 4, and 5..Each of these transfer devices consists of aframework having an opentop and bottom with side members 5 5. This frame is preferably cast inone piece with the connecting-webs 6 and 7 at its ends. Each side memberis provided with bottom shoes 8 8, which travel upon the top face of thechannel-web and fit loosely against the flanges, and at the top areprovided U-shaped straps or abutments 9 and 10, which are bolted to thelateral flanges 11 of the casting. Within the movable frame abovedescribed is located a shifting frame having pivoted to its ends theropesockets 12 12. This shifting frame is provided with a front shoulder13, which is adapted to butt against the web 6 in certainpositions, andalso with a rear shoulder 14, adapted to butt against the web 7 incertain positions. The side members 15 of the shift.- ing frame fitloosely between the side mem bers 5 5 of the outer frame and receive thepin 16, to which the dog 17 is pivoted and also the abutment-pin 18.These pins are held in place by the side members 5 5 of the outer frame.The shifting frame rests upon the webs 6 and 7 andin its rear portion ispivoted the depending gravity-latch 19, the

pivot-point of this latch being above the abutment 7. The upper end ofthe dog 17 projects above the top of the hotbed-rails a sufficientdistance to insure a proper movement of the metal when the entire deviceis I(Olrawn from the delivery-rollers onto the hot- At the side of thedelivery-roller opposite to the hotbed are located a series of shelvesor supportinguides 20, having downwardlyinclined nose portions 21.

22 indicates one of the pulleys or drums around which the wire rope 23passes, the

ends of this wire rope being secured to the rope-sockets 12.

In the operation of the device a pulling strain applied to the movingframe in a direction to cause it to travel from the rollers to thehotbed will first pull the inner shifting frame into position shown inFig. 3, in which position the dog of each frame will be elevated bygravity, the forward movement of the shifting frame being stopped by theshoulder 13 abutting against the web 6. A further pulling movementcauses the elevated dogs to push the metal forwardly upon the hotbed.After the metal has been moved forwardly to the desired point on thehotbed the movement of the wire ropes is reversed, and the strain beingapplied in the opposite direction to the shifting frame willfirst slidethis shifting frame rearwardly within its inclosing frame until theshoulder 14 strikes the web 7. In this movement the nose of the dog willstrike the abutment 10, which will depress the dog into the positionshown in dotted lines. Immediately thereafter the latch 19 will be swungup by movement over the abutment 7 and will hold the ment with thenotched portion 24 of the tail of the dog.

will be held depressed.

The dogs of the several frames will thus be depressed without contactingwith any beams or metal in the rear of the dogs and in its return-path.As long as the movement of the dog-supports is continued in this returndirection, therefore, the dogs If it is desired to lock the dogs in thisdepressed position, so that they may be held in such position duringtheir forward travel, so as to pass them under certain beams or metallying on the rollers or table, he dog-carriers are moved back to aposition where the shelves will hold the tails of the dogs and preventthe dogs tilting to raised position. A forwardpulling movement upon theropes will then draw the dogs and their shifting frames along on theshelves until the noses of the dogs are brought under the frontabutments 9 of the outer frame. In this position as long as the framesare drawn steadily forward the dogs will remain depressed and are heldagainst tilting up by the abutments 9. Now if it is desired to throw thedogs into ope1 ative position the operator shifts the direc tion ofrotation of the rope drums or pulleys so as to move the shifting framesback a slight distance, when the dogs will be released and will tiltinto operative position, and the movement of the drums being againreversed to draw the frames forwardly the dogs will then act upon themetal in front of them. The dogs are held in proper upright position bythe stoppins 18. It will therefore be evident that the operator may lookthe dogs whenever desired and then by a quick backand-forth movement canrelease the dogs at any point desired in the width of the hotbed. Theswinging latch acts to insure the depressing of the nose of the dogsufficiently to clear the metal. If this were not used, the abutment 10may become worn by continual use, so that it would allow the dogs to.project slightly above the top of the hotbed even when acted upon bythese webs 10. The latch also acts to depress the dog far enough toengage under the abutment 9.

The advantages of my invention will be apparent to those skilled in theart. The

dogs are depressed without forcibly striking beams or metal with whichthey may contact on their backward return movement, and thus areprevented from nicking or injuring the beams or other metal. Theshiftingframe device enables the operator to lock the dogs at the rearportion of their travel and then hold them locked until any desiredpoint in the width of the hotbed is reached. He can then release thedogs, and thus select any beam or metal upon which he desires to act.The latch device insures the proper holding of the dogs in depressedposition.

Many variations may be made in the form and arrangement of the partswithout departing from my invention, since I consider myself the firstto depress the dogs without contacting with the metal operated upon andalso the first to provide means for lockin the dogs and releasing themat any desire point without manual operation.
